Abstract
Метод за регенериране на крекингкатализатор, съгласно патент на българия n 25981, включващ след ните стадии: контактуване на катализатора, съдържащ кокс с пресен регенериращ газ до образуване на плътен слой флуидизиран катализатор; прибавяне на пресен регенериращ газ при температура от 620 до 760'с към окислен кокс от катадизатора, отделящ частично регенериран катализатор и употребен регенерационен газ, съдържащ со; възходящо пренасяне на катализатор в разредена фаза; допълнително кислородно довършване на изгарянето на со до со2 и повишаване на температурата на разредената фаза в границата от 677 до 774'с, характеризиращ се с това, че катализаторът съдържа от 0,01 до 20% ускорител на превръщане на со, избран от металите ванадий, хром, манган, желязо, кобалт, мед и техните окиси от 0,5 до 200 обемни ррм на благороден метален окис, избран от платинов и паладиев окис. Патентните претенции са формулирани в 3 точкиA method for regenerating a cracking catalyst, according to Bulgarian patent n 25981, including the following stages: contacting the catalyst containing coke with fresh regenerating gas until a dense layer of fluidized catalyst is formed; adding fresh regeneration gas at a temperature of 620 to 760°C to oxidized coke from the catalyzer, separating partially regenerated catalyst and spent regeneration gas containing salt; uplift of dilute phase catalyst; additional oxygen completion of the combustion of CO to CO2 and raising the temperature of the dilute phase in the range of 677 to 774°C, characterized in that the catalyst contains from 0.01 to 20% of a CO conversion accelerator selected from the vanadium metals , chromium, manganese, iron, cobalt, copper and their oxides from 0.5 to 200 ppm by volume of a noble metal oxide selected from platinum and palladium oxide. The patent claims are formulated in 3 points
